Thrillist is reporting that in order to redeem your prize, you have to download the company's app then create a new account. Afterwards, you order a sandwich and pay by entering your card information on the app.

Once all of this is done, the promotion automatically loads onto your account.

The promotion will end after the restaurant chain gives away all 75,000 sandwiches nationwide.

Users can order any kind of sandwich they choose to and those who download the app for the first time will receive a free cookie with their meal.
